Angus Gratton 73879734d9 esp8266: Update port to use new event functions.
This is necessary to avoid watchdog timeout in long i2c.scan(), as
previously machine_i2c.c would call MICROPY_EVENT_POLL_HOOK if
MICROPY_EVENT_POLL_HOOK_FAST was not available.

Compared to previous implementation, this implementation removes the
ets_event_poll() function and calls the SDK function ets_loop_iter() from
MICROPY_INTERNAL_EVENT_HOOK instead.  This allows using the port-agnostic
functions in more places.

There is a small behaviour change, which is that the event loop gets
iterated in a few more places (i.e. anywhere that mp_event_handle_nowait()
is called).  However, this looks like maybe only modselect.c - and is
probably good to process Wi-Fi events in that polling loop.

Damien George cc8fc450a6 esp8266/modmachine: Use common implementation of disable/enable_irq.
Now that the MICROPY_BEGIN_ATOMIC_SECTION/MICROPY_END_ATOMIC_SECTION macros
act the same as disable_irq/enable_irq, it's possible to use the common
extmod implementation of these machine functions.

Damien George e1ec6af654 extmod/modmachine: Provide common bindings for 6 bare-metal functions.
Minor changes for consistency are:
- nrf gains: unique_id(), freq() [they do nothing]
- samd: deepsleep() now resets after calling lightsleep()
- esp32: lightsleep()/deepsleep() no longer take kw arg "sleep", instead
  it's positional to match others.  also, passing 0 here will now do a 0ms
  sleep instead of acting like nothing was passed.
  reset_cause() no longer takes any args (before it would just ignore them)
- mimxrt: freq() with an argument and lightsleep() both raise
  NotImplementedError

Damien George 7d39db2503 extmod/modmachine: Factor ports' machine module dict to common code.
This is a code factoring to have the dict for the machine module in one
location, and all the ports use that same dict.  The machine.soft_reset()
function implementation is also factored because it's the same for all
ports that did already implement it.  Eventually more functions/bindings
can be factored.

All ports remain functionally the same, except:
- cc3200 port: gains soft_reset, mem8, mem16, mem32, Signal; loses POWER_ON
  (which was a legacy constant, replaced long ago by PWRON_RESET)
- nrf port: gains Signal
- qemu-arm port: gains soft_reset
- unix port: gains soft_reset
- zephyr port: gains soft_reset, mem8, mem16, mem32

Damien George 5b4a2baff6 extmod/machine_uart: Factor ports' UART Python bindings to common code.
This is a code factoring to have the Python bindings in one location, and
all the ports use those same bindings.  For all ports except the two listed
below there is no functional change.

The nrf port has UART.sendbreak() removed, but this method previously did
nothing.

The zephyr port has the following methods added:
- UART.init(): supports setting timeout and timeout_char.
- UART.deinit(): does nothing, just returns None.
- UART.flush(): raises OSError(EINVAL) because it's not implemented.
- UART.any() and UART.txdone(): raise NotImplementedError.

Damien George 60929ec7e2 extmod/machine_wdt: Factor ports' WDT Python bindings to common code.
There are currently 7 ports that implement machine.WDT and a lot of code is
duplicated across these implementations.  This commit factors the common
parts of all these implementations to a single location in
extmod/machine_wdt.c.  This common code provides the top-level Python
bindings (class and method wrappers), and then each port implements the
back end specific to that port.

With this refactor the ports remain functionally the same except for:

- The esp8266 WDT constructor now takes keyword arguments, and accepts the
  "timeout" argument but raises an exception if it's not the default value
  (this port doesn't support changing the timeout).

- The mimxrt and samd ports now interpret the argument to WDT.timeout_ms()
  as signed and if it's negative truncate it to the minimum timeout (rather
  than it being unsigned and a negative value truncating to the maximum
  timeout).

Jim Mussared 94beeabd2e py/obj: Convert make_new into a mp_obj_type_t slot.
Instead of being an explicit field, it's now a slot like all the other
methods.

This is a marginal code size improvement because most types have a make_new
(100/138 on PYBV11), however it improves consistency in how types are
declared, removing the special case for make_new.

Damien George 39d50d129c ports: Add SoftI2C and SoftSPI to machine module where appropriate.
Previous commits removed the ability for one I2C/SPI constructor to
construct both software- or hardware-based peripheral instances.  Such
construction is now split to explicit soft and non-soft types.

This commit makes both types available in all ports that previously could
create both software and hardware peripherals: machine.I2C and machine.SPI
construct hardware instances, while machine.SoftI2C and machine.SoftSPI
create software instances.

This is a breaking change for use of software-based I2C and SPI.  Code that
constructed I2C/SPI peripherals in the following way will need to be
changed:

    machine.I2C(-1, ...)            ->  machine.SoftI2C(...)
    machine.I2C(scl=scl, sda=sda)   ->  machine.SoftI2C(scl=scl, sda=sda)

    machine.SPI(-1, ...)            ->  machine.SoftSPI(...)
    machine.SPI(sck=sck, mosi=mosi, miso=miso)
                        ->  machine.SoftSPI(sck=sck, mosi=mosi, miso=miso)

Code which uses machine.I2C and machine.SPI classes to access hardware
peripherals does not need to change.

Damien George 8f20cdc353 all: Rename absolute time-based functions to include "epoch".
For time-based functions that work with absolute time there is the need for
an Epoch, to set the zero-point at which the absolute time starts counting.
Such functions include time.time() and filesystem stat return values.  And
different ports may use a different Epoch.

To make it clearer what functions use the Epoch (whatever it may be), and
make the ports more consistent with their use of the Epoch, this commit
renames all Epoch related functions to include the word "epoch" in their
name (and remove references to "2000").

Along with this rename, the following things have changed:

- mp_hal_time_ns() is now specified to return the number of nanoseconds
  since the Epoch, rather than since 1970 (but since this is an internal
  function it doesn't change anything for the user).

- littlefs timestamps on the esp8266 have been fixed (they were previously
  off by 30 years in nanoseconds).

Otherwise, there is no functional change made by this commit.

machine.Timer now takes a new argument in its constructor (or init method):
tick_hz which specified the units for the period argument.  The period of
the timer in seconds is: period/tick_hz.

For backwards compatibility tick_hz defaults to 1000.  If the user wants to
specify the period (numerator) in microseconds then tick_hz can be set to
1000000.  The user can also specify a period of an arbitrary number of
cycles of an arbitrary frequency using these two arguments.

An additional freq argument has been added to allow frequencies to be
specified directly in Hertz.  This supports floating point values when
available.
